Abstract

In this paper, we review selected imaging and related technology development programs in the Defense Advanced Research Projects Agency (DARPA) Microsystems Technologies Office (MTO). An overview is presented for the evolution of Joule-Thomson (J-T) micro-cryogenic cooler (MCC) technology. The initial design of a system on a chip method is shown for these micro-coolers to be used in conjunction with high operating temperature mid-wave infrared (MWIR) and long-wave infrared (LWIR) focal plane arrays. For the reflective visible band, results are shown for a gigapixel monocentric multi-scale camera design to solve the scaling issues for high pixel count and wide field of view. Lastly, we discuss two different approaches to multiband imaging and the potential advantages of this technology for the enhanced detection, recognition, and identification of targets.
